On-Board Diagnostics
Fig. 14 Locat io n of Data Link Co nnec tor (DLC)
On-Board Diagnostics monitors the compo­
nents o f your emission control system. Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, the component will be identified
and the fault stored as a code in the control module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem. If the light illuminates after a refuelling,
stop the veh icle and make sure the fuel filler
cap is properly closed
c:> page 220.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD) .
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the right of the hood release
c:> fig . 14.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair .
Electronic speed limiter
Your vehicle may be factory equipped with
tires that are rated for a maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of s udden tire failure and loss of control if the vehicle is operated at excessive speeds,
your vehicle a lso has an e lectronic speed limit­
er . The e lectronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. For more information
c:> page 249.
If the engine control unit receives faulty vehi­
cle road speed signals, the Ma lfunction Indi­
cator Lamp (MIL)
(lllli$ will illuminate . If this
occurs, contact the nearest authorized Audi
dealer for assistance .
_&. WARNING
-Always observe the posted speed lim its
and adjust your speed to suit prevailing r oad, traffic and weather cond itions. Never
drive your vehicle faster than the maxi­ mum speed rating of the tires installed.
